Numerical Simulation of Gas-Liquid Two-Phase Flow in Multi-Impeller Pre-Oxidation Reactor

Abstract:

Numerical simulation of gas-liquid two-phase flow in the tank of multi-impeller pre-oxidation reactor was studied in this article. The dispersion of gas phase in liquid phase without agitator mixing and the distribution of gas-liquid two-phase flow with agitator mixing were simulated. The characteristics of gas-liquid two-phase flow and the regularities of the gas distribution in the reactor were achieved through analyzing the numerical simulation results. The dissolved oxygen in different cross sections of the reactor without agitator mixing was measured in the water test, which was used to verify the numerical simulation results. And the test results were almost the same with the simulation results, which can provide a reference for determining the optimum design parameter of this type of reactor.
